The epiteth is used as a noun in apposition. Type locality. Samoylov Island, Lena river delta (72°22’22”N 126°28’47”E); wet moss; water temperature 3.9°C; conductivity 54 μS/cm; pH 7,22; September 10, 2019; coll. A. Novikov. aterial examined. Holotype: female, dissected and mounted on 2 slides (ZM&G BP 541/1-a; 541/1-b). Allotype, male dissected and mounted on one slide (541/2). Paratypes: one female dissected and mounted on one slide (541/3), and two females and one copepodite V preserved in formalin (541/4). Description. Female holotype. Body almost cylindrical, vermiform. Total body length of holotype from tip of rostrum to posterior margin of caudal rami: 0.419 mm. Cuticle very thin. Body colourless. Naupliar eye not discernible. Cephalothorax (Fig. 1) as wide as remaining somites. With cuticular window on cephalothorax dorsally, and on P2-bearing somite laterally. Rostrum small, fused to cephalothorax. Posterior margin of all somites smooth. Cephalothorax with 27 pairs of sensilla and 4 pairs of pores. Second pedigerous somite with 5 pairs of sensilla, and one paired and one unpaired pore. Third pedigerous somite with 6 pairs of sensilla, and one unpaired pore. Fourth pedigerous somite with 5 pairs of sensilla, and single pore. Fifth pedigerous somite with 3 pairs of sensilla. Pedigerous somites 2-5 with rows of small spinules dorsally and laterally. Genital-double somite (Figs. 2A, B) wider than long with dorsolateral rows of spinules; with 6 pairs of sensilla, and 1 pair of lateral pores, 1 pair of ventral double-pores and one unpaired dorsal pore. P6 strongly reduced to 1 pinnate seta. Genital field dense, with massive chitinous thickenings, and one pore and one short spinular row on each side; copulatory pore large; copulatory duct wide and short. Nodular thickening (arrow in Fig. 2B) round, ... |
